Cattle tick infestations constitute a major problem for the cattle industry in tropical and subtropical regions of the world. Traditional control methods have been only partially successful, hampered by the selection of chemical-resistant tick populations. The Boophilus microplus Bm86 protein was isolated from tick gut epithelial cells and shown to induce a(More)
BACKGROUND In most patients with atrial fibrillation (AF) and stroke, there is thrombotic embolization from the left atrial appendage (LAA). Percutaneous closure of the LAA is a novel alternative for the treatment of patients with AF at a high risk of stroke, in whom long-term anticoagulation therapy is not possible or not desired. This study details the(More)
OBJECTIVES To examine the clinical characteristics and outcomes of cancer patients with venous thromboembolism (VTE) in order to identify factors that place these patients at an increased risk for fatal pulmonary embolism (PE) or fatal bleeding. PATIENTS AND METHODS Registro Informatizado de la Enfermedad Trombo Embólica (RIETE) is a prospective registry(More)
Atrial fibrillation (AF) is a common complication after coronary artery bypass grafting. Atrial remodeling has been observed in AF and has been associated with the development of this arrhythmia. Because 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins) have been demonstrated to modify remodeling, we hypothesized a protective role of statins(More)
The objective of this study was to evaluate prognostic factors and the influence of different empiric antibiotic therapies on outcome and mortality in a cohort of 100 inpatients with bacteraemia (84 cases nosocomial) caused by methicillin-resistant Staphylococcus aureus (MRSA). Patients were investigated by means of a standard protocol at a 944-bed hospital(More)
PURPOSE There are no recommendations as to whether endoscopic evaluation of the upper gastrointestinal tract is indicated in asymptomatic patients who have a positive fecal occult blood test and a negative colonoscopy. SUBJECTS AND METHODS All asymptomatic patients with a positive fecal occult blood test who were referred for diagnostic endoscopy were(More)
AIMS To study the long-term prognostic value of red blood cell distribution width (RDW) in patients hospitalized with acute heart failure (AHF) and to compare the value of this measurement with haemoglobin levels and anaemia status. METHODS AND RESULTS During a 2-year period, we studied 628 consecutive patients (aged 71 years [interquartile range, IQR:(More)
Although the endocrine response to psychological stressors has been extensively studied both in animals and humans, the sensitivity of these variables to the intensity of stress experienced by exposure to psychologically stressful situations has not been studied in humans. In the present work this was assessed by measuring plasma levels of glucose, cortisol(More)
The aim of this study was to evaluate the association between heart rate turbulence (HRT) parameters and clinical, biochemical, echocardiographic, and electrocardiographic measures of heart failure (HF) in a large, prospectively enrolled population of patients with HF to determine whether HRT could be considered a marker of HF advancement and progression,(More)
UNLABELLED There are limited data on the prognostic role of biomarkers in anticoagulated patients with atrial fibrillation (AF). We evaluated the prognostic value of high sensitivity TnT (hsTnT) and high-sensitivity interleukin-6 (hsIL6) in a large cohort of AF patients taking oral anticoagulant therapy (OAC) as both biomarkers have been associated with(More)
